Description

Technical Field

[0001] The utility model relates to the technical field of phosphoric acid tail gas treatment, in particular to a phosphoric acid tail gas treatment component. Background Art

[0002] As we all know, there are two main methods for producing phosphoric acid: wet process and thermal process. Wet process phosphoric acid is produced by treating phosphate rock with sulfuric acid or other inorganic acids, while thermal process phosphoric acid is produced by producing elemental phosphorus in an electric furnace or blast furnace and then burning and hydrating it.

[0003] Phosphoric acid tail gas treatment devices purify the gas under the action of a catalyst to reduce environmental pollution. When the high-temperature phosphoric acid tail gas passes through a metal catalyst carrier, harmful substances in the tail gas undergo a chemical reaction under the action of the catalyst and temperature, converting them into non-toxic water or gas. However, existing phosphoric acid tail gas treatment devices cannot adjust the reaction speed according to the phosphoric acid tail gas flow rate. Utility Model Content
